A powerful cold front and upper level trough pushed across the Upper Ohio Valley on July 10th producing widespread severe weather and flash flooding from eastern Ohio, northern West Virginia, and western Pennsylvania. This included 3 separate tornadoes. One tornado occurred in Lawrence county, PA, with 2 additional tornadoes across portions of Tuscarawas and Carroll counties in Ohio.

This is a continuation of a tornado that originally touched down in Tuscarawas county and crossed into Carroll county near Atwood Lake. See Storm Data for Tuscarawas county Ohio for details on this tornado. This tornado produced EF-0 to EF-1 damage from south of Bolivar to near Atwood Lake, before crossing into Carroll county near Atwood Lake, and producing EF-0 damage to trees before dissipating south of Delroy. Maximum winds with this tornado were estimated to be from 90 to 100 MPH, with a path length near 14 miles. The maximum path width was near 300 yards.

An NWS storm survey found an EF-1 tornado that touched down northwest of Kilgore and dissipated southwest of Amsterdam in Carroll county. Damage was first noted along Route 332 south of Petersburgh, OH where trees were downed or snapped off. This damage continued southeast along Aster Road, with low end EF-1 damage to hardwood trees. Tree damage continued along Raindrop Road and Pronto Road, with high end EF-1 damage to trees along Pronto road. Damage then rapidly ended near Cavalry Road as the tornado dissipated. Maximum winds were estimated to be from 100 to 110 MPH, with a path length near 9 miles. The maximum path width was 150 yards.

Lead time is measured from the issue of the warning in force to the touchdown time in the database, both of which were recorded to the minute by different people.

The Storm Prediction Center had this point in a Slight Risk, with a 0.02 chance of a tornado within 25 miles. The outlook in force was issued at 19:59 UTC.

SPC's Day 1 convective outlook as it stood when the tornado began, read at the touchdown point. The same archive is on the radar archive.

The radiosonde launches on either side of the tornado, from the nearest station that was launching then, drawn and analyzed the way Storm Lab does: the same diagram, the same parcel and shear definitions SPC's mesoanalysis uses.

The Pittsburgh radar (KPBZ), 69 km away, was scanning. The volume nearest the touchdown began at 21:07 UTC.

Ratings are the survey's, read off the damage rather than measured; the rating scale is above. Tornado counts rise through the record as reporting improved, so a year in the 1950s is not comparable with one today except for the strongest tornadoes, which were always noticed.
